Application-filed June 6, 1912. Serial No. 702,039.

To all whom it may concern Be it known that l, Enwann CARLSON, a 'citizen of the United States, .residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Ad justable Window-Screens, of which the following is a specification.

My invention relates 'to window screens of the adjustable type and has for its object the provision of an improved'means for helding the screen fabric on the frame, and also an improved construction of the slidable portions of the screen.

Myinvention will be described in detail hereinafter and illustrated in the accom the well known extensible screen comprising two sections slidably engaging one another and consists essentially in constructing said sections of metal, and in the drawings the two sections are indicated at 1 and 2. Each of the sections 1 and 2 is provided with rectangular frames on which are mounted the screen fabric 3, said frames having three of their sides formed of bars 4 around which the screen fabric 3 is secured, while the remaining side of the frame consists of a sheet of metal indicated at 5 inclosing the edge of the screen fabric 3, and as shown in Fig. 5, formed in a threefold to securely clamp said edge.

Mounted on the bars 4 are plates shown in Figs. 3 and 4E and indicated at 6 and 7 respectively, said plates being bent to inclose said frame bars t on three sides, and having one of the edges of the plates provided with an int-urned lip designated 8 and 9 on the two plates 6 and 7 respectively, to securely clamp the screen fabric on the frame. The other edges of the plates 6 on the upper and lower rails ofthe section 1,

are extended on a plane substantially parallel with the screen fabric 3, as shown at 10 and formsone member of the sliding element of the screen sections, while the corresponding edges of the plates 7 on said upper and lower section 2, are bent back on themselves as shown at 11 to engage the By this construction, it will be apparent that the plates 6 and 7 used for-clamping the screen fabric on the screen frames performs the double function of holding the screen fabric in place on the frame and also forming the sliding members for the screen.

Having thus described my invention, What I claim is 1. In an adjustable window screen, frames, screen fabric mounted on said frames, plates inclosing said frames and portions 10 of the plates 6.

clamping the edges of the screen fabric' thereon, the plates on the upper and lower rails of one section having one of their edges extended substantially parallel with the screen fabric on the corresponding frame, and the corresponding edge of"the plates on the upper and lower rails of the other section having their edges bent back on themselves to slidably engage the extended edge of the plates on the first mentioned section.

2: An adjustable window screen comprising frames, sheets of screen fabric mounted on said frames, plates mounted on said frames and inclosing the edges of the screen fabric and the frames, one' of the edges of Paten'ted reb. 4, 191s.

said plates having an inturned flange engaging said screen fabric, the plates on the upper and lower rails of one of said sections having its edge farthest removed f-nom the flanged portion extended on a plane sub stantially parallel to the screen fabricon the frame, the plates on the upper and lower rails of the other frame having the edges farthest removed from the flanges thereon bent back on themselves and slidabl engaging the corresponding edges 0 the plates on the first mentioned frame.

. In testimony whereof I alfix my signature in presence of two witnesses".
